DISCUSSION
KEY MESSAGE 1: PREVAILING HIGH PRESSURE WILL YIELD MINIMAL RAIN
CHANCES THROUGH MID-WEEK WITH ABOVE NORMAL TEMPERATURES.
ZONAL FLOW EARLY WEEK WILL TRANSITION TO A STRENGTHENING RIDGE
PATTERN ALOFT, WHILE SFC HIGH PRESSURE HOLDS ACROSS THE LOCAL AREA
FOR MUCH OF THE WEEK. THE PATTERN WILL SUPPORT A WARMING TREND AS A
RESULT, WITH LATEST GUIDANCE SUPPORTING HIGH TEMPS IN THE LOW-MID
80S AWAY FROM THE COAST (SEA BREEZE INFLUENCES) TUESDAY THROUGH
THURSDAY. CONDITIONS ARE ALSO EXPECTED TO REMAIN DRY FOR A BULK OF
THE WEEK, ALTHOUGH WEAK H5 VORT ENERGY COULD HELP PRODUCE LIGHT
PRECIP ACTIVITY ACROSS THE INTERIOR WEDNESDAY AFTERNOON.
A COLD FRONT COULD APPROACH THE REGION LATE IN THE WEEK, BRINGING A
HIGHER POTENTIAL FOR MEASURABLE RAINFALL THIS UPCOMING WEEKEND.
AVIATION /06Z MONDAY THROUGH FRIDAY/
VFR CONDITIONS WILL PREVAIL AT CHS/JZI/SAV TERMINALS THROUGH 06Z
TUESDAY.
EXTENDED AVIATION OUTLOOK: VFR CONDITIONS ARE EXPECTED AT
CHS/JZI/SAV TERMINALS THROUGH MID-WEEK. TEMPO FLIGHT RESTRICTIONS
POSSIBLE AT ALL TERMINALS WITH DAILY SHOWERS AND/OR THUNDERSTORMS
DURING THE UPCOMING WEEKEND.
MARINE
PRIOR TO DAYBREAK: THE PRESSURE GRADIENT WILL CONTINUE TO WEAKEN
ACROSS LOCAL WATERS WHILE HIGH PRESSURE DOMINATES THE PATTERN ACROSS
THE REGION. THIS WILL SUPPORT IMPROVING CONDITIONS ACROSS ALL WATERS
THROUGH DAYBREAK. LATEST WIND/SEA OBS HAVE ALREADY DROPPED BELOW
SMALL CRAFT ADVISORY CRITERIA ACROSS NEARSHORE SC WATERS, AND WILL
LIKELY FALL BELOW THIS CRITERIA ACROSS NEARSHORE GA WATERS PRIOR TO
SUNRISE. A SMALL CRAFT ADVISORY WILL CONTINUE TO OUTER GA WATERS DUE
TO LINGERING 6-8 FT SEAS.
TODAY AND TONIGHT: HIGH PRESSURE WILL CONTINUE TO DOMINATE THE
WEATHER PATTERN ACROSS THE SOUTHEAST UNITED STATES, FAVORING WIND
CONDITIONS WELL BELOW SMALL CRAFT ADVISORY LEVELS ACROSS LOCAL
WATERS. HOWEVER, LINGERING 5-7 FT SEAS WILL BE SLOW TO SUBSIDE
ACROSS OUTER GEORGIA WATERS, WHERE A SMALL CRAFT ADVISORY IS
ANTICIPATED TO PERSIST INTO TUESDAY MORNING.
EXTENDED MARINE: HIGH PRESSURE WILL PERSIST ACROSS THE REGION
THROUGH LATE WEEK, SUPPORTING WINDS/SEAS THAT REMAIN BELOW SMALL
CRAFT ADVISORY CONDITIONS. THE EXCEPTION WILL BE ACROSS OUTER GA
WATERS, WHERE 6 FT SEAS COULD LINGER INTO MID MORNING HOURS TUESDAY,
THEN POSSIBLY REBUILD TO 6 FT AGAIN THURSDAY NIGHT INTO FRIDAY AS A
FRONT APPROACHES THE SOUTHEAST UNITED STATES LATE WEEK.

GA...NONE.
SC...NONE.
MARINE...SMALL CRAFT ADVISORY UNTIL 6 AM EDT EARLY THIS MORNING FOR
